Abstract (en)
[origin: US2016033226A1] A firearm with barrel extension comprises a receiver, a barrel supported by the receiver that defines an ammunition shell chamber, and a rotatable locking bolt having radial bolt lugs. The bolt is carried by a slide disposed in the receiver for forward and rearward movement. A barrel extension is mounted on a rear end of the barrel which includes radial bolt locking lugs that rotatably engage the bolt lugs when the bolt is in a closed locked breech position in battery with the head of a chambered shell. The barrel extension includes a rear facing annular rim seating surface formed integrally on the barrel extension as a unitary structural part thereof. The rim seating surface extends radially inwards from an interior surface of the barrel extension to engage and support the rear rim of the chambered shell. The headspacing is defined entirely by the barrel extension independently of the barrel.
